Electrical Characteristics

1、discharge capacity at normal temperature:After full charge, the experiment can be put on hold for 10 minutes; 0.2C discharge to 2.5V allows five repetitions. When the range of three consecutive experiments is less than 3% of the rated capacity, the experiment can be completed ahead of time and the maximum value of the test results can be obtain。

2、Discharge performance at different temperatures:After standard charging of normal batteries, it should be stored at least 12 hours in the constant temperature environment of – 20 ℃, – 10℃, 0℃, 10 ℃ and 25 ℃, respectively, and 5 hours of 60 ℃. Then discharge with 0.5C current to the corresponding termination voltage. When the ambient temperature is more than 15 ℃, the termination voltage is 2.5V, if less than 15 ℃, which is 2.0V.
